More on the death of "space-time" as fundamental

"....Beyond making calculations easier or possibly leading the way to quantum gravity, the discovery of the amplituhedron could cause an even more profound shift, Arkani-Hamed said. That is, giving up space and time as fundamental constituents of nature and figuring out how the Big Bang and cosmological evolution of the universe arose out of pure geometry.

 

“In a sense, we would see that change arises from the structure of the object,” he said. “But it’s not from the object changing. The object is basically timeless.”

Howdy Josh,

 

Yeah, the mainstream's ideas of space and time are all goofed up. It is all simple stuff IMO that they have not figured out as yet. Space is simply the distance between matter and nothing more. Rene De Carte described space as an extension of matter. Time is also a simple concept. Time is simply an interval of change that clocks measure, and nothing more.  Space-time is a good concept that Einstein invented. Since everything in space is moving relative to everything else, there is no absolute point in space to reference the locations of stars and galaxies. We compensate this by knowing a particular location relative to the background of distant galaxies which appear to stand still relative to everything more local. Then we plot changes in location relative to time. This way we can plot the changes of something's location in space over time and make excellent predictions. To make these calculations they need both measurements in space, and how much time has passed since their last measurements.  Since all such calculations require measurements in both of space and time, the collective Einstein called Spacetime,

 

This supposed Jewel of quantum theory (first link), if simpler , might be better or easier for calculation, but both space and time are obviously fundamental and are certainly different parts of reality, The concept of space-time as being one thing is simply a perspective of reality, but not something fundamental, somewhat in line with the first link.

 

Of course it all depends upon the point of view being used. The above point of view in your two links relate to Quantum Mechanics, which may be the most ridiculous theory in modern physics IMHO. Parts of it have also have been called "quantum quackery." It is simply based upon theoretical physics, primarily statistics.  It makes the primary predictions of the probability of events at the atomic-particle lever of reality. Such as, for example, a 50-50 chance this or that will happen, one or the other, but not many exact predictions of anything else. This is because mainstream theorists have little understanding of the quantum world IMHO. I have attaching a link to a related paper that I wrote that was published online by Researchgate, and has been read by 800 educated readers so far, roughly 15 to 20 more readers each week. The main perspective that it follows is that everything in reality is logical and relatively simple to understand, mathematics aside. One does not have to understand the mathematics in the link below, only the logic of it if one is interested in "logical" arguments in physics like the arguments in the links above.

Josh, I watched the video. The author's perspective is from neuroscience. The concept of spacetime is a perspective in physics, many  or most in physics understand that it has no fundamental meaning. Only space and time as separate entities have fundamental meanings as part of reality.

What's beyond spacetime? has a different meaning in physics than what the author in the link is portraying. Yes, Groupthink is involved in the concept of spacetime as being fundamental, where many theorists and astronomers realize that spacetime as being a single entity only fits well with the math and can be better understood as two separate entities. But Beyond Spacetime in physics generally means outside space and time. So, what is outside space and time. As explained in my previous post, space is simply the distance between matter. So if there is no matter or field there is no space. Similarly, time is defined as an interval of change. If there is no matter or field that can change, there also is no time.

 

So beyond spacetime there would be nothing at all. Even more precisely, many or most physicists would say that Beyond space and time does not exist at all since there could be no such thing, place or existence.

There's pretty graphic illustration of what they're talking about in the video. But I'll map it out below: 

 

"Conscious Agents" > "Decorated Permutations" > "Amplituhedron (all of this exists in a timeless state) > "Space-Time Geometry."

 

Below or beyond space-time, which is referred to as akin to a virtual reality headset, are geometric shapes like the Amplituhedron. That is what gives geometry to the space-time headset. Further below the amplituhedron is a more fundamental level of the decorated permutations. Which give geometry to the amplituhedron. 

 

And everything which is more fundamental than the space-time headset, is in a timeless state. This is where beyond space-time derives from.
